Illumination device
First Claim
1. An illumination device, having at least four luminous units (1, 2), the light emitted by at least two of the four luminous units (1, 2) being suitable for being mixed to form white light, and an apparatus (3) suitable for dimming at least one of the four luminous units (1, 2).

Abstract
An illumination device comprising at least four luminous units (1, 2), the light emitted by at least two of the four luminous units (1, 2) being suitable for being mixed to form white light. Moreover, an apparatus (3) for dimming at least one of the four luminous units (1, 2) is provided. White light having a desired color temperature (CCT) and a high color rendering index can be generated by means of the illumination device.

7. An illumination device, having
a first light-emitting diode module (1) comprising at least one light-emitting diode suitable for emitting light in the red spectral range, at least one light-emitting diode suitable for emitting light in the green spectral range, and at least one light-emitting diode suitable for emitting light in the blue spectral range, a second light-emitting diode module (2) comprising at least one light-emitting diode suitable for emitting light in the yellow spectral range, an apparatus (3) suitable for generating pulse-width-modulated signals for driving at least one portion of the light-emitting diodes, and a control apparatus (4), by means of which at least one predefined correlated color temperature (CCT) of the light emitted by the illumination device can be set.
